From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- .../execute/intrinsic_rrspacing.f90 | 29 ++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 gcc/testsuite/gfortran.fortran-torture/execute/intrinsic_rrspacing.f90 (limited to 'gcc/testsuite/gfortran.fortran-torture/execute/intrinsic_rrspacing.f90') diff --git a/gcc/testsuite/gfortran.fortran-torture/execute/intrinsic_rrspacing.f90 b/gcc/testsuite/gfortran.fortran-torture/execute/intrinsic_rrspacing.f90 new file mode 100644 index 000000000..e74cf6494 --- /dev/null +++ b/gcc/testsuite/gfortran.fortran-torture/execute/intrinsic_rrspacing.f90 @@ -0,0 +1,29 @@ +!Program to test RRSPACING intrinsic function. + +program test_rrspacing + call test_real4(3.0) + call test_real4(33.0) + call test_real4(-3.0) + call test_real8(3.0_8) + call test_real8(33.0_8) + call test_real8(-33.0_8) +end +subroutine test_real4(orig) + real x,y,orig + integer p + x = orig + p = 24 + y = abs (x * 2.0 ** (- exponent (x))) * (2.0 ** p) + x = rrspacing(x) + if (abs (x - y) .gt. abs(x * 1e-6)) call abort +end + +subroutine test_real8(orig) + real*8 x,y,t,orig + integer p + x = orig + p = 53 + y = abs (x * 2.0 ** (- exponent (x))) * (2.0 ** p) + x = rrspacing(x) + if (abs (x - y) .gt. abs(x * 1e-6)) call abort +end -- cgit v1.2.3
